| Abstract: | In this study,according to the production procedure of two powdered infant formula(PIF)processing plants in Shaanxi Province,raw materials,workshop environment,processing equipment and the soil around the factory were sampled to investigate the prevalence of Cronobacter spp.The Cronobacter isolates were further subtyped via pulse field gel electrophoresis(PFGE)to trace the contamination points of Cronobacter spp.during PIF processing.Fourteen(1.12%)Cronobacter spp.positive samples were detected in 1246 samples collected previously and 33 Cronobacter isolates were recovered.The 33 isolates were subtyped into 14 genotypes with the similarity of 85.9%-100.0%.Combining the PFGE subtyping results and milk powder processing procedure,we conclude that the lactose powder,the staff sole,the soil around factory,the package workshop,the air inlet and purification system,the workshop gutter might be the potential key Cronobacter contamination points.The results of this study provide basic information for Cronobacter contamination sources identification and control during PIF production. |
